M
echanical and electrical (M&E) services require fire
protection for the following reasons:
1) To maintain function of certain essential electrical
and/or mechanical systems and services, and
2) To prevent fire, smoke and toxic fume propagation
from one building compartment to another.
It is necessary to ensure the continued function of essential electrical
systems and services is maintained during fire, for a specified period
of time, until all the building occupants have escaped. Electrical
systems that need protection from fire may include:
 Smoke extraction venting systems
 Electrically operated fire alarms
 Water mains supply and pumps servicing sprinkler systems
 Emergency escape route lighting
 Essential life support and/or computer, communication or
information technology networks
 Electrically operated extinguishing systems
 Power supply for fire service elevators in high-rise buildings

General Information
It is worth noting that most electrical and to some extent mechanical
services contain a high component of plastic materials such as
polyvinylchloride, polypropylene, polyethylene, synthetic rubbers etc.
The risks associated with these combustible plastics are such that
fire can and will spread or propagate through the services. Intensive
combustion also means that plastics frequently release toxic and
corrosive fumes that can include particulates, unburned fuel, carbon
dioxide and carbon monoxide which are not only harmful to the
building and its contents but also to its occupants. Such fires can also
cause the following problems:
 Production of highly corrosive and extremely toxic gases,
 Long term destruction of buildings and equipment,
 Smoke development and toxic gases in corridors and
escape routes,
 Difficult evacuation,
IEC 60331 fire test
 Impedance of rescue activities by firefighters.
Reliability Of Fire Resistant Cables
requirement to maintain the integrity of the encasement and any
penetrations through walls or floors, the standard requires that:
Typical uses of cables to, in and from M&E enclosure include fire
alarms, emergency lighting, addressable alarm systems, CCTV
systems, emergency power supplies and smoke and fire shutters.
These cables are normally designed to meet the standards for “Fire
Detection and Fire Alarm Systems for buildings” (BS 5839: Part 1:
2002 + A2: 2008) and “Codes of Practice for Emergency Lighting of
Premisses” (BS 5266: Part 1: 2005).
1) the cables continue to function for the duration of the exposure
period, and
Many fire resistant cables have been subjected to tests in accordance
with BS 6387: 1994 “Specification for performance requirements for
cables required to maintain circuit integrity under fire conditions” and/
or ISO IEC 60331: Parts 11, 21, 23 and 25 “Test for electric cables
under fire conditions – circuit integrity”. See also ISO IEC 60331: Parts
1, 2 and 3.
2) the temperature on the cable jacket should not exceed 150°C.
The tested encasement system protects a wide range of different
cable types. Electrical current is passed through the cables throughout
the test. As an added safety factor, the system described on page 6
will ensure that the temperature on the cable jacket does not exceed
120°C.
Unfortunately, these standards only test single cables or small
bunches of cables, without any support system, exposed to a small
gas flame by means of an elongated Bunsen burner. The heat applied
during the test is localised to a small area. While such a test may be
adequate for small cables carefully secured directly to a fire resisting
wall or floor, it is arguably not suitable to assess the fire performance
of larger cables or bunches of cables, exposed to a fully developed
fire on all sides, especially if they are supported on a suspended cable
tray which may pass through compartment walls or floors.
The Australian/New Zealand standard AS/NZS 3013: 2005 “Electrical
installations – Classification of the fire and mechanical performance
of wiring system elements” describes the level of protection of a
wiring system against fire and/or accidental mechanical damage. The
test methods described within this standard call for wiring systems
to maintain circuit integrity when subjected to fire tests, mechanical
damage and fire and water tests. The resistance to fire test is to
determine the ability of a wiring system to maintain circuit integrity
under fire conditions for a specified period of time of up to 120
minutes. The wiring system shall be tested in a horizontal furnace
complying with AS 1530: Part 4: 2005, which also employs the ISO
834 heating conditions.
Although the cables may achieve the highest classification of the
standard, they may not survive as expected if they are exposed on all
sides to a fully developed fire as described, for example, by the ISO
834 time-temperature fire curve.
Mechanical damage tests are to determine the degree of mechanical
impact and cutting load to which the wiring system can be subjected
without losing its circuit integrity. These tests are carried out
separately from the fire test.
Fire Resistance Test Standards
For Cable Protection Systems
The German standards DIN 4102, “Fire behaviour of building materials
and building components”, Parts 11 and 12 specify fire resistance
test for cable protection systems that simulate a fully developed
fire scenario.
Fire and water tests assess the ability of a wiring system to maintain
its circuit integrity when subjected to fire conditions followed by
hosing with water.
DIN 4102: Part 12: 1991 and AS/NZS 3013: 2005 are designed to test
the functionality of cables under fully exposed fire conditions, unlike
the IEC 60331 test regimes. The systems detailed herein relate to
maintaining compartmentation as well as the full function of the cables.
For more information related to such systems, please consult Promat.
DIN 4102: Part 11: 1985 assesses the encasement system when
exposed to a fully developed internal fire. The integrity of the
encasement, and any penetrations through walls and floors, is
measured, as well as the temperature on the outer surface of
the encasement (140°C mean temperature rise, 180°C maximum
temperature rise). The heating curve for DIN 4102: Part 11: 1985 is the
same as that used in BS 476: Part 20: 1987 and AS 1530: Part 4: 2005
and the failure criteria for integrity and insulation are identical. The
systems detailed herein have been successfully tested and assessed
and are approved for use to provide a performance in accordance with
BS 476: Part 20 and AS 1530: Part 4 in terms of compartmentation.
In the event of an internal or external fire performance, it has been
established that an enclosure fabricated from fire resistant boards
is one of the best solutions. Such systems have been tested
successfully with encasement constructed from fire protective boards
such as PROMATECT -H, PROMATECT -L, PROMATECT -L500,
PROMATECT 50 or PROMATECT -S. These well established board
systems are representative of the few systems which currently fulfil
all performance requirements, especially to the DIN 4102 standards.
DIN 4102: Part 12: 1991 assesses the encasement system when
exposed to a fully developed external fire. In addition to the

General Design Considerations
6 Access Hatches
A suitably designed duct will:
For future inspection and installation of cables, a loose lid construction,
described on pages 6 and 7, can be considered. Alternatively, the
lid can be fixed and the inspection openings with hatches can be
provided in the side walls of the enclosure, as shown on page 9. The
hatch is secured completely to the enclosure using threaded inserts
such as “Tecserts” (Armstrong Fastening Systems) at maximum
200mm centres.
 prevent the propagation of fire from one building compartment
to another,
 assist in maintaining smoke free escape routes,
 ensure the continuing operation of other services within a common
service shaft,
 reduce damage to a localised area,
 contain smoke and toxic fumes from burning cables, and
 where required, ensure cable maintain their function when exposed
to a fully developed fire.
7 Selection of Board Type
The Promat system constructed from PROMATECT®-H,
PROMATECT®-L or PROMATECT®-L500 is lighter than PROMATECT®
50, and would probably be used in most applications.
The following are some of the factors to consider when determining
the correct specification to ensure the enclosure system provides the
required fire performance. Please consult Promat.
PROMATECT®-H or PROMATECT® 50 offers a particularly robust
system which is also highly resistant to impact and abrasion. Although
these products are water tolerant, the latter is generally preferred for
more onerous conditions.
1 Required Fire Exposure
For tunnel environments and higher performance requirements, e.g.
to resist hydrocarbon fires, please consult Promat.
The specification of the enclosure system will depend on whether it is
expected to resist external fire, internal fire or both.
8 Other Requirements
2 Required Fire Performance
Generally, the most onerous requirement is to maintain the functional
integrity of the circuit(s) when the system is exposed to external fire.
If this is not needed, the performance requirements may be reduced
by the approval authority to provide only stability, integrity and
insulation of the enclosure system and/or wall and floor penetrations.
On some occasions, further relaxations may be approved, e.g. a
reduced insulation performance can sometimes be acceptable if no
combustible materials or personnel are likely to be in contact with the
enclosure.
3 Supporting Structure
The supporting hangers and their fixings should be capable of bearing
the load of the complete enclosure system including any applied
insulation material or other services suspended from it. Chemical
anchors are generally not suitable. It is usually not advisable to
employ unprotected hangers if the stress exceeds 6N/mm2 for up to
240 minutes fire exposure and 10N/mm2 for up to 120 minutes fire
exposure and/or if hanger lengths exceed 2m. Hanger centres should
not exceed the distance limits given for the relevant Promat system.
4 Penetrations Through Walls & Floors
Care should be taken to ensure that movement of the cable system
in ambient or in fire conditions does not adversely affect the
performance of the wall, partition or floor penetration seals.
5 Ventilation Openings
Heat is generated as current flows through cable core conductors. The
greater the electrical current, the hotter the conductor will get. Excessive
current flow will cause overheating and may result in overload, short
circuit or ground fault. The material of the cable sheath, commonly made
from material such as PVC, polyurethane or polyethylene, usually has a
self-ignition temperature between 340°C to 490°C.
In general, the heat generated by cables is negligible if appropriately
vented. Ventilation openings must have a self-enclosing capability in
the event of fire so as to prevent fire spread via such openings. It is
recommended that an electrical engineer is consulted to ensure heat
build-up does not become an issue. Should ventilation be required,
see page 9 for PROMASEAL® Ventilation Grille and Promat Ventbox.
Acoustic performance, thermal insulation, water tolerance,
strength and appearance can also be important considerations
(see BS 8313: 1997 Code of practice for accommodation of building
services in ducts).
Fibre Optics
Fibre optic cables have a lower failure temperature (typically 50-80°C)
due to the fact that the conductor consists bundles of glass fibres
which can be as thin as a human hair. Fibre optic cables are widely
used for IT networking in many industries, especially in financial
and healthcare services. For example, large banks depend on
their network cabling systems for most of their routine business
transactions. If fire occurs and even one metre of cabling is destroyed,
it could cost the company millions of dollars each day their systems
remain inoperative. These are problems that businessmen do not
want to face and one reason why it is necessary to protect sensitive,
strategically important cables against fire risk. Please consult Promat
to determine the required board thickness and construction details.
Riser Pipes
The Fire Safety Bureau of Singapore requires that the pipe work for a
rising main is adequately protected to prevent collapse and reduction
of water pressure at the point of water egress in the event of a fire. In
addition, fire will heat the water conveyed through the piping system.
It is conceivable that water in the pipe could reach boiling point. This
would result in additional pressure being placed upon the pipe system
as water expands considerably (1:1700) as it turns to steam. This will
result in premature failure of the pipes and joints transporting the
water, leading to a loss of pressure and consequential inability to fight
or extinguish the fire. Therefore it is required that the rising main pipe
work is adequately protected to:
 prevent collapse of the piping system,
 maintain the fire integrity and insulation of the compartment wall or
floor where the piping penetrates, and
 prevent water passing through the piping system from reaching
boiling point. The temperature at any point on the pipe external
surface, measured on the fire-exposed side, must not exceed
75°C above the initial temperature for at least the first 30 minutes
of exposure to fire.
The fire resistance test procedure is described in FSB/PSB/001/00
dated 8 November 2000.

Internal Cross Section Dimensions
The Promat cable protection system is fabricated from
PROMATECT®-H, PROMATECT®-L or PROMATECT®-L500 boards
with thickness according to the tables on pages 6 and 7. The boards
can be fixed together with steel staples at maximum centres of
100mm or screws at maximum centres of 200mm in accordance with
the table below. Up to three layers of boards can be used to fabricate
the required thickness.
The internal cross section of the enclosure system shall not be more
than 1000mm wide x 500mm high. Please consult Promat for cross
sections not within this range.
This is a self-supporting system and does not require any internal
steel framework (subject to width and height of the enclosure not
exceeding set limits).

Joints between the sections of enclosure are reinforced with
external cover strips of PROMATECT®-H, PROMATECT®-L or
PROMATECT®-L500 board, each 100mm wide and a minimum of
9mm thick. The cover strips are fixed with steel staples or screws.
Cables And Enclosure Support
Cables are normally supported on steel cable trays within the
enclosure but these are not always required when the enclosures are
subject to internal fire exposure only.
The enclosure system must be supported, either by direct fixing to
other structural elements with suitable proprietary steel fixings or
by hangers at maximum centres of 1220mm. The hanger supports
should coincide with enclosure joints. The hangers consist of steel
threaded rods and a steel angle bearer section under the protection
system. The tensile and bending stresses of the unprotected hangers
and bearers must not exceed 10N/mm2 for up to 120 minutes fire
resistance.
One, Two or Three Sided Protection
A one, two or three sided enclosure is acceptable where the other sides of the rectangle are formed from an adjoining wall and floor/ceiling
of a fire resistance at least equal to that of the enclosure system, and where under fire conditions the substrates will suffer no deflection or
excessive movement.

Internal Steel Framework
Building Services And Enclosure Support
The corner junctions of the enclosure are reinforced with internal
steel angles, minimum size according to system specification. These
corner angles are not necessary if boards of thickness 20mm and
above are used, as the boards can be fixed to
each other using deep thread drywall type
screws or steel wire staples.
The hangers used to support the building services enclosure
must have tensile and bending stresses not exceeding 15N/mm2,
10N/mm2 and 6N/mm2 for fire resistance up to 60, 120 and 240
minutes respectively. If these stress levels are exceeded, the size of
the hanger members must be increased or, alternatively, the spacing
of the hangers reduced.
The fixings used to fasten the threaded hanger rods to concrete
soffits must be all steel expanding anchors with at least 80mm
length penetrating into the concrete of at least 40mm for 120
minute fire resistance and 60mm for 240 minute fire resistance.
The anchors must match the size of the threaded rods, be of
sufficient strength to support the weight of the enclosure and be
fitted in accordance with the manufacturer’s specification. When
the hanger rods are suspended from protected structural steel
beams, the rods must be protected for at least 300mm from the
beams with the same levels of protection as the structural beams.
External steel angle
Internal steel angle
Four-sided steel channel collars are positioned at approximately
1220mm centres to support the boards. The steel channels are of
minimum size 50mm x 25mm x 0.5mm, up to 50mm x 50mm x 1.2mm
thick depending on the system specification.

Steel channel framed enclosure
Fixing of Boards & Mineral Wool
The type of board and thickness shall be selected according to system
specification and the required fire resistance level. The boards are
fastened to the channel frames and corner angles with self-tapping
screws of appropriate length at 200mm nominal centres.
For systems where corner angles are not used, i.e. for 20mm or
thicker boards, the boards are to be fastened at the corners with
steel self-tapping screws at 200mm nominal centres or steel staples
at 100mm nominal centres as per the below table.

Longitudinal joints in the boards (other than the corner joints) must
be backed by a steel channel. All butt joints, as required by system
specification, are covered with 100mm x 9mm thick PROMATECT®-H
cover strips that may be placed either externally or internally.
The cavity between the boards and the building services is filled
with mineral wool with thickness and density corresponding to the
system’s requirement. The steel channels are also filled with the same
mineral wool. See the illustrations of Collar section with external or
internal cover strips.
Collar section with internal cover strips
Where the hangers exceed 2000mm in length, the hangers should be
clad with a material of similar thickness to the enclosure to prevent
excessive thermal expansion.
Where the hanger rods emerge from the enclosure, the hole/slot must
be sealed with PROMASEAL®-A Acrylic Sealant and with or without
a cover plate depending on the gap at penetration. Please consult
Promat when in doubt.
If the building service being encased is a plastic pipe, external hangers
and angles will be required to independently support the enclosure.

is 6000mm wide x 2500mm high. For enclosures with internal
dimensions greater than 1500mm x 1500mm, additional threaded
rods are fitted at each hanger position, at 1220mm maximum centres
across the width of the enclosure. These threaded rods pass through
the enclosure and support the horizontal hanger support element
beneath the enclosure. The rods also support the top of the enclosure
using a nut and large steel washer, this prevents bowing under fire
conditions of wide enclosure systems.
As the width of the enclosure system increases, the spacing of
the channel collars must be reduced so that the maximum area of
unsupported board does not exceed 1.5m2.
Typical enclosure up to 6000mm wide x 2500mm high
The penetrations of the rods through the enclosure are sealed with
PROMASEAL®-A Acrylic Sealant.
Please note, the requirements for additional hanger support within
the duct for greater width, e.g. 6000mm duct, will require two
central supports at maximum 1220mm centres.
One, Two or Three Sided Protection
One, two or three sided enclosures are constructed in the same way
as a four sided enclosure. Steel angles of 50mm x 50mm x 0.9mm
thick and 3mm thick for up to 120 and 240 minutes fire protection
respectively, are fastened to the floor soffit or wall with M8 all steel
expanding anchors at 500mm nominal centres. The PROMATECT®-H,
PROMATECT®-L500 or PROMINA® 60 boards forming the walls of the
protection to the building services are then fastened to the angles with
steel self-tapping drywall type screws in appropriate length at 200mm
nominal centres. The services are independently supported.

Transformation Sections
The figure to the right shows a common
transformation section. Where board joints abut
at an angle and it is not possible to back the
joint with steel channels, angles bent to the
appropriate degree are used to back
these joints.
The steel channels should always
be placed to limit the total
unsupported area of board to
a maximum of 1.5m2. Bends
or curved shapes must be
supported with hangers at
mid-span.
Vertical Enclosures
Access Panels
The construction of vertical enclosures is the same as for the
horizontal enclosures. Where a vertical enclosure is located adjacent
to a wall, the enclosure should be restrained back to the wall with
threaded rods and support sections.
Maximum allowable dimensions of access panels are 600mm x
600mm. The panels are fixed to the enclosure through steel channels
using steel bolts and nuts at nominal 200mm centres. The thickness
of the boards and the mineral wool specifications should be according
to system requirements. The mineral wool can be encapsulated within
the C-channel sections which in turn are fixed to the access panel by
means of steel self-tapping screws.
Enclosure
The weight of the enclosure assembly must be fully supported at
each floor level. Steel angles may be fitted to the enclosure at floor
penetration level and sit upon the floor slab, supporting the weight of
the enclosure.
